Vestil CST-VE-PUA Series casters are ideal for transporting heavy-material in both indoor and outdoor environments. These polyurethane units are bonded to a lightweight, aluminium core for excellent impact resistance and low-frictional rolling in both smooth and rugged flooring. They further come integrated with hardened bearing raceways that help to distribute loads evenly and covered seals to resist dust and debris, thereby preventing fretting. Choose from an array of these casters, available in rigid and swivel variants on Raptor Supplies.
